Tsubaki Super (Heavy Duty) Drive Chains
Super (Heavy Duty) Drive Chains

Tsubaki Super (Heavy Duty) Drive Chains offer high maximum allowable loads for use in compact systems

Tsubaki offers a variety of heavy duty and Super Chains to provide users with a higher maximum allowable load, higher shock absorption, higher fatigue strength, and higher tensile strength than standard RS Roller Chains. This enables users to go one or two sizes down to design more compact systems.

Application

High impact/load applications
Compact drives for equipment or machinery that must work in tight spaces
When higher transmission power, allowable tension, or tensile strength is required
When a lower rate of elastic elongation is required
e.g., Construction machinery, farm equipment, lifting mechanisms, port equipment, tower parking, etc.

Features and Use

Item/Model	Super Roller Chain	RS-HT Chain	Super-H Roller Chain	Ultra Super Chain
Main applications	For heavy-duty transmission, lifting
Features	High kW ratings High shock absorption Can use one size smaller RS Roller Chain	High kW ratings High tensile strength	High fatigue strength High tensile strength High shock absorption	Ultra Super Chains have the highest tensile strength and shock absorption of any Tsubaki roller chain. For drives that require compact designs. Able to use two sizes smaller RS Roller Chain.
Features	Note) Tsubaki Heavy Duty Roller Chains are designed for low to medium speed transmission. RS Roller Chain should be used in high speed applications that are not described.
Example applications	e.g. Construction machinery, farm equipment, lifting mechanisms, port equipment, tower parking, etc.
Offset links	4POL can only be used for single-strand chain.	Offset links are not available. Use an even number of links.
Sprocket	Sprockets for RS Roller Chain can be used for multi-strand and single strand chain.	Sprockets for RS Roller Chain can be used for single strand chain. Sprockets for RS Roller Chain cannot be used for RS-HT multi-strand chain and Super-H Roller Chain.
Sprocket	Small sprockets must have hardened teeth. Use sprockets made of S35C or higher carbon steel. Sprockets for RS Roller Chain can be used if the usage conditions and chain size of the chain being replaced remain the same. Tough Tooth sprockets that are optimal for Heavy Duty Chain are available.
